In the last 100 years, the world has been going through a very bad time. The world is going through a deep crisis due to the epidemic caused by the COVID-19 virus, millions of people are being infected and dying. The whole world economy has collapsed. In the midst of all this, the cryptocurrency is in the opposite situation. By 2020, cryptocurrencies will be part of history, breaking all past records. With the advent of the Defi project and the rise of cryptocurrency, the cryptocurrency will be memorable. I believe that in 2021, cryptocurrency will be better in continuation of this.
